Another thought after re-reading your post TR.... You say hunt hard from sunup till 9 am and then from 4 on. Having worked in a Taxidermy shop I have also seen just as many buck be brought in that were shot between 10 and 2 during the rut as the times you listed. I think better advice would be "if you can sit in the woods during the rut than you should sit" because during the rut you are just as likely if not more so to see bigger buck during all hours of the day as you will during the times you listed. I hunt out of state where there is nothing else to do during hunting hours other than hunt so I sit all day during most the days I am there and while the opening of the season and late season are slow during the late morning/ noon hours, the days during rut are always more exciting with very little slow times as compared to the rest of the season. Understand this is hunting in a state where there are more deer than what I see in Pa, would I be as willing to sit all day in Pa??? Probably not because I can hunt a 2 weeks straight in your average woods of Pa and not see the quantity or quality deer I see hunting 2 days in the average woods of the midwest.
